Not really on 'latency' per se as discussed in the articole but an interesting take on slow terminals is Casey Muratori's famous rant on the topic [0] that led him to write his own terminal [1], a reference renderer for monospace terminal displays that is several orders of magnitude faster than Windows Terminal despite being largely unoptimized.
I feel very sad! Everything I loved about music had always ties with him, his style and his type of production. I was so excited about the upcoming Shellac album and tour. This hits so heavy... :(
